There is definitely nothing particularly spectacular about Rack Shack BBQ, other than the idea that you can get beef brisket and other smoked meats in an unlikely location -- outside of Phoenix's best small-show venue (The Rhythm Room).
For that, I appreciate the business minds who are behind the concept, where the same target audience would be satisfied with drab provisions, like hot dogs wrapped in bacon and flimsy-meat burgers. Instead you can partake in one of the oldest method of preparing meats, either in a full-plate format, or on a seedless hamburger bun.
BBQ from Rack Shack is a great way to kill an hour or so while the opening band clangs through "hits" only groupies would love.
